Electrical musical instrument



H. s. MILLS ELECTRICAL MUSICAL INSTRUMENT Filed March 251 1924 ly resist the additional movement. The the circuit 8 may control the bow-depressparts may be so arranged and pi-ormrtionml that the spring (3" will be brought under ini tial tension by the time the circuit 8 is closed, and thus tend to resist further 1norcment of the key. Under extra eliort in the pressing of the hey, however, the spring 6, which new acts cui'nulatirely with the spring 5 yields to permit the additional movement, thus allowing the treinolocireuit to be closed.

1th the arrangement described, it is possible for the player to strike the keys with suliicient force to close the playing-circuits, without fear or, at the same time, closing the tremolo-circuit. At any time desired, however, the operator may strike the key with additional force, thus effecting the increased amplitude oi" naneinent and closing the tremolo-circuit.

In practice, the circuit 8 n .y control the application of the lingers and or the bow to the string, thus sounding the note, assuming the musical apparatus to be of the type where the bow is continuously driven and requires only to be depressed to bring it into contact with the string when the note is to be sounded. Thus, in the example given,

inn" magnet and linger-magnet.

The tremolo-circuit 10 may control a tremolo device oi any suitable construction and ar 'angenient, where such device adapted for electrical control.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claim should be construed as broadly permissible in View of the prior art.

l l hat I regard as new, and desire to secure by Letters Patent, is:

In means of the character set forth, a tulcrunied key, a playing-circuit contact mounted on the inner end thereo't' and a tremolo-circuit contact mounted in front of said first-named contact, a eo-acting contact for each circuit, a spring holding said key under normal tension for playing, and a second spring having one end connected with a stationary member and having the other end connected with said hey, one of said connections being a slotted lost-motion connection.
